The contribution regards a simulation model of the conversion process of an azo-dye (Acid Orange 7) in a Pseudomonas sp. OX1 biofilm reactor under steady state aerobic/anaerobic conditions. The reaction network embodies: phenol conversion under aerobic conditions, oxygen depletion as a consequence of cells uptake – growth and maintenance contributes - dye conversion under anaerobic conditions. The conversion kinetics were assumed in agreement with previous investigations: substrate inhibition kinetics with respect to the phenol consumption; Monod type kinetics with respect to the oxygen; Michaelis-Menten type kinetics as regards dye conversion, provided that anaerobic conditions established. Simulation results were reported in terms of phenol, oxygen and dye concentration throughout the bioparticle.

Abstract
The contribution regards a simulation model of the conversion process of an azo-dye (Acid Orange 7) in a Pseudomonas sp. OX1 biofilm reactor under steady state aerobic/anaerobic conditions. The reaction network embodies: phenol conversion under aerobic conditions, oxygen depletion as a consequence of cells uptake – growth and maintenance contributes - dye conversion under anaerobic conditions. The conversion kinetics were assumed in agreement with previous investigations: substrate inhibition kinetics with respect to the phenol consumption; Monod type kinetics with respect to the oxygen; Michaelis-Menten type kinetics as regards dye conversion, provided that anaerobic conditions established. Simulation results were reported in terms of phenol, oxygen and dye concentration throughout the bioparticle.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
